Question

please give me fast answer​

Answer 1

Step-by-step explanation:

a^m x a^n = a^m+n

1. 3^7 x 3^8= 3^ 7+8 = 3^15

2. 2^5 x 2^(-6) = 2^5+(-6) = 2^ (-1) = 1/2

3. (1/2)² x (1/2)³ x (1/2)⁻²= (1/2)²⁺³⁻² = (1/2)³ = 1/8

4. 4⁻³ x 4³ = 4³⁻³= 4⁰= 1

5. 3⁴x3⁻⁵= 3⁴⁻⁵= 3⁻¹= 1/3

6. (-5)²x (-5) x (-5)⁻² x (-5)= (-5)²⁺¹⁺¹⁻²= (-5)² = 25

7. m⁸ x m³x m²ⁿ= m⁸⁺³⁺²ⁿ= m¹¹⁺²ⁿ

8. a⁶ x a⁻³ x a⁻⁴= a⁶⁻³⁻⁴= a⁶⁻⁷= a⁻¹= 1/a

9. 2⁸ x 2⁶x 2⁻¹⁰x 2⁴= 2⁸⁺⁶⁻¹⁰⁺⁴= 2⁸ = 256

10. 3⁹ x 4⁶ x 4⁸x 3⁻² = 3⁹⁻² x 4⁸⁺⁶= 3⁷ x 4¹⁴

                                                   = 3⁷ x 4⁷ x 4⁷

aⁿx bⁿ= (axb)ⁿ

                                                  = (3x4x4)⁷ = 48⁷

           Hope it is helpful. Take care.
