(- 1) to the power of 2010 + the power of π to the power of 0 - (1 / 3) to the power of - 1 + the third power of 8

(- 1) to the power of 2010 + the power of π to the power of 0 - (1 / 3) to the power of - 1 + the third power of 8
=1+1-3^1+2
=4-3
=1

Root 64 + the third power of minus 8 + root 25=

Root 64 + the third power of minus 8 + root 25
=8-2+1
= 7

How much is the minus fourth power of the root eight equal

The root 8 is three-thirds of 2, so the answer is a quarter

What is the root 8 + 2 times sin 30 degrees - 4 times cos 45 degrees

Solution: root 8 + 2 times sin 30 degrees - 4 times cos 45 degrees
=√8+2sin30-4cos45
=2√2+2×1/2-4×√2/2
=2√2+1-2√2
=1

Given that the a power of 2 = 3, the B power of 8 = 6, find the quantitative relationship between a and B

8^b=(2^3)^b
=2^3b=6
2^a=3
(2^3b)/(2^a)=2^(3b-a)=2
3b-a=1

Given that 2A = 3, 2b = 6, 2C = 12, try to judge the relationship between a, B, C

∵ 2A = 3, 2b = 6, 2C = 12, and 6 × 6 = 62 = 3 × 12,
∴（2b）2=2a×2c=2a+c，
∴2b=a+c．
