Find the value of X in the following formulas. (1) 16 ^ 2-x = 8 ^ x + 5; (2) 3.6 * 10 ^ x = 0.36

Find the value of X in the following formulas. (1) 16 ^ 2-x = 8 ^ x + 5; (2) 3.6 * 10 ^ x = 0.36

(1)
16^（2-x）=8^（x+5）
8^4-2x=8^x+5
4-2x=x+5
-3x=1
x=-1/3
(2)3.6*10^x=0.36.
10^x=0.1
x=-1

How to solve the proportion such as X: 6.5 = 6:4 5:8 = x: 160.3 / 1.5 = 4.2 / x 5 / 3: x = 2:3 / 2 2 / 1:4 = 10 / 1: x 7 / 2 = x / 8

x：6.5=6:4
x=6.5*6/4
x=9.75
5:8=x：16
x=5*16/8
x=10
0.3/1.5=4.2/x
x=1.5*4.2/0.3
x=21
5/3:x=2:3/2
x=3/5*2/3/2
x=1/5
2/1:4=10/1:x
x=4*1/10/1/2
x=4/5
7/2=x/8
x=7*8/2
x=28

Solution ratio 5: x = 30:3 X: 4 = 5:48 3:8 1 of 4 = x: 2 1.5:4 3 = 0.36: X
Write the formula

5：x= 30:3
30X＝3*5
30X=15
X＝0.5
x:4=5:48
48X＝4*5
48X＝20
X = 5 / 12
3 / 4:1 / 8 = x: 2
1 in 8 = 2 * 3 in 4
1 in 8 = 3 in 2
X＝12
1.5:3 / 4 = 0.36: X
1.5x = 3 / 4 * 9 / 25
1.5x = 27 / 100
X = 9 / 50
