Question 1.

Question 2.
Can you find two integers m and n such that 2m+“ = 2m”?
Answer:
m + n = mn
2 + 2 = 2 x 2
4 = 4
∴ m = 2 & n = 2

Question 3.
If (2^m)⁴ = 4⁶ find the value of m.
Answer:
(2^m)⁴ = 4⁶ (a^m)ⁿ = a^mn
(2^m)⁴ = 4⁶
(2^m)⁴ = (2²)⁶
2^{m × 4} = 2^{2 × 6}
2^4m = 2¹²
∴ 4m = 12
m = 
m = 3
