1. If x power of 10 = 2, y power of 10 = 3, then x + y power of 10=____ 2. If x + 2 power of 3 = 36, then x power of 3=___ .

1. If x power of 10 = 2, y power of 10 = 3, then x + y power of 10=____ 2. If x + 2 power of 3 = 36, then x power of 3=___ .

1. If x power of 10 = 2, y power of 10 = 3, then x + y power of 10=_ 6_.
2. If x + 2 power of 3 = 36, then x power of 3=_ 4_.

Calculation: divide by 8 × 2 and 2 × 1 of 15 (2 × 0.28 of 6 and 3 + 0.72 × 6 and 2 of 3),

8 × 2 of 15 and 1 of 2 (2 × 0.28 of 6 and 3 + 0.72 × 6 and 2 of 3)
=8 / 15x5 / 2 △ {6 and 2 / 3x (0.28 + 0.72)}
=4/3÷20/3
=1/5

It is known that the parabola y2 = 2px (P > 0) intersects the straight line y = x + 1 with two points a and B, and the circle with chord length AB as the diameter just passes through the origin

A and B are in the first quadrant, and the circle with the chord length AB as the diameter is certainly not the origin

Simple calculation of 4 / 5 minus (7 / 10 minus 13 / 20)

4/5 - ( 7/10 - 13/20 )
= 16/20 - 14/20 + 13/20
= 16/20 - 1/20
= 15/20
= 3/4
perhaps
= 0.8 - 0.7 + 0.65
= 0.1 + 0.65
= 0.75
= 3/4

The square of X - 4x + 2 is formulated in three different ways

The square of X - 4x + 2 = (X-2) ^ 2-2

17 × 12 = 238 how to move a match?
Move only one match

2 to 4,
17×14=238
The top of 2 becomes 4 when it is placed vertically and horizontally

If the image of the power function f (x) passes through the point (4.2), then the value of F (16) is,

f(x)=x^a
Then 2 = 4 ^ a = 2 ^ (2a)
So 2A = 1
a=1/2
Then f (16) = 16 ^ (1 / 2) = 4

Simple operation of 237-45 + 63-55

237-45+63-55
=（237+63）-45-55
=300-（45+55）
=300-100
=200

The first time I poured two-thirds and 80 grams of oil, I poured back 140 grams. The second time I poured three-quarters, I still had 90 grams. How many grams of alcohol in all

For the first time, 90 △ 1-3 / 4 = 360 G
Total (360 + 80-140) / (1-2 / 3) = 300 / 1 / 3 = 900g
