- ( 42 x 229 ) ÷ ( 9261)^1/3 = ?
Question 1:
( 42 x 229 ) ÷ ( 9261)^1/3 = ? A. 456
B. 457
C. 458
Feedback Given that, (42 x 229) ÷ (9261)^1/3 = ?
As we know that (9621)^1/3 = (21 x 21 x 21)^1/3 = 21^3x1/3
∴ 42 x 229 ÷ (21^3 x )^1/3 = ?
∴ 42 x 229 ÷ 21 = ?
∴ 42 x 229 x 1/ 21 = ?
∴ 2 x 229 = ?
∴ ? = 2 x 229
∴ ? = 458
