Question

Tolong bantu no 1 e, g, h, i, j, k, o, p, r, s, v

Answer 1

E) √(x² + 2x + 1) = √(x + 1)² = x + 1

g) (√27)^(-2/3) + 5^2/3 + 5^1/3
= (3^3/2)^(-2/3) + 5^1/3 (5^1/3 + 1)
= 1/9 + ∛5 (∛5 + 1)

h) ∛(x - 2)⁻² 
utk x = -6 -> 1/∛(-8)² = 1/4

i) √18 + √50 - √72 = 3√2 + 5√2 - 6√2 = 2√2

j) 4√75 + 3√(4/3) - 2√48 = 20√3 + 6√(1/3) - 8√3
= 12√3 + 6√(1/3)

o) log ∛10 = x
log 10^(1/3) = x
1/3 log 10 = x
x = 1/3
