Answer:
1. x⁵ • x² = x⁷
Explaination : Add the exponent of a variable when multiply. Subtract the exponent when dividing variables.
Ex.: 2x • x² = 2x³
4x³ ÷ 2x = 2x²
2.2x • 2x • 2x • 2x • 2x or (2x)⁵ = 32x⁵
Explaination : ✓ 2•2•2•2•2 = 32
✓ x•x•x•x•x = x⁵
3. (3)² • 2 = 18
Explaination: ✓ (3)² = 9
✓ 9 • 2 = 18
4. 5⁵/5⁵ = 1
Simplification:
✓ 5•5•5•5•5/5•5•5•5•5
✓3,125/3,125 = 1
Explaination: Dividing a number itself, the answer is always 1.
Ex.: 102 ÷ 102 = 1
5. 100⁰ = 1
Explaination : Any number that raise to the power of 0 or have an exponent of 0, is equal to 1.
Ex.: 146290⁰ = 1
822⁰ = 1
