A) 4.7
B) 1.41
C) 5
D) 6
Correct Answer: C
Solution :
\[\frac{{{(4.7)}^{3}}+0.027}{{{(4.7)}^{2}}-1.41+0.09}\] \[=\frac{{{(4.7)}^{3}}+{{(0.3)}^{3}}}{{{(4.7)}^{2}}-4.7\times 0.3+{{(0.3)}^{2}}}\] \[=\frac{(4.7+0.3)[{{(4.7)}^{2}}-4.7\times 0.3+{{(0.3)}^{2}}]}{{{(4.7)}^{2}}-4.7\times 0.03+{{(0.3)}^{2}}}=5\]You need to login to perform this action.
