Question

@CLASS 9 MATHS Chapter number system question number 2 solution.@:-)

Answer 1

Hey friend,

(1) (√4)^2x+½ = 1/32

→(2)^2x+½ = 1/32

→2^(2x+½) = 1/2^5

→ 2^2x+½= 2^-5

Bases are equal. Exponents must be equal.

2x+½= -5

(4x+1)/2 = -5

4x+1 = -10

4x = -11

x = -11/4

(2) √(3/5)^1-2x = 4 17/27

→ (3/5)^(1-2x)×½ = 125/27

→ (3/5)^(1-2x)×½ = (5/3)³

→ (3/5)^½-x = (3/5)^-3

Bases are equal. Exponents must be equal.

1/2 - x = -3

1/2+3 = x

x = (1+6)/2

x = 7/2

Hope it helps
