Which equation is equivalent to 4sqrt x+3=64?

B

Step-by-step explanation:

Given

= 64

Using the rule of exponents

= , then

Expressing and 64 in base two

= = and 64 = , thus

=

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
