✔ 最佳答案
You need to use parentheses. Can't tell if you mean√(2x+5) = 13
or
√(2x) + 5 = 13
or
(√2)x + 5 = 13
For √(2x+5) = 13:
2x + 5 = 13²
2x = 164
x = 82
For √(2x) + 5 = 13:
√(2x) = 8
2x = 8²
x = 32
For (√2)x + 5 = 13:
(√2)x = 8
x = 8/√2
= 4√2

√(2x) + 5 = 13
√(2x) = 13 - 5
2x = 8^2
x = 64/2
x = 32
√(2x) = 13 - 5
2x = 8^2
x = 64/2
x = 32

√(2x) + 5 = 13
Simplify:
√(2x)=8
Square both sides:
2x=8^2
Simplify:
2x=64
x=32
Simplify:
√(2x)=8
Square both sides:
2x=8^2
Simplify:
2x=64
x=32
