Answer:
x = 9
Step-by-step explanation:
Using the rule of exponents
×
⇔ 
Given
=
×
=
= 
Since the bases on both sides are common, then equate the exponents
x = 9
The factors of 56: 1; 2; 4; 7; 8; 14; 28; 56
The factors of 84: 1; 2; 3; 4; 6; 14; 28; 42; 84
GCF(56; 84) = 28
5x-25=5, x=6; multiply the 5 times x and negative 5, then add 25 to both sides, and divide by 5 to get 6.
