Question

Nilai dari ( ⁵㏒₃ . ⁹㏒√₁₂₅ + ⁵㏒₂₅ / ²㏒₁₆ - ²㏒₄ )² =
a. 121/64
b. 81/64
c. 36/64
d. 27/64
e. 12/64

Answer 1

= [(⁵㏒3 x ⁹㏒√125) + (⁵㏒25 / ²㏒16) - ²㏒4]²

= [(⁵㏒3 x 1/2.3/2.³㏒5) + 2/4 - 2]²

= [(3/4 x ⁵㏒3 x ³㏒5) - 3/2]²

= [(3/4 x ⁵㏒5) - 3/2]²

= [(3/4 x 1) - 3/2]²

= [3/4 - 3/2]²

= [3/4 - 6/4]²

= [- 3/4]²

= 9/16

= 36/64
