$(7)^3 ÷ (49)^2 × 343 = 7^{(? – 2)}$
Answer: (a)
$(7)^3 ÷ (7^2)^2 × 7^3 = 7^{? – 2}$
⇒$7^{3 – 4 + 3} = 7^{? – 2}$
⇒? – 2 = 2⇒? = 4
$(5)^2 × (25)^3 × 125 = (5)^{?}$
Answer: (d)
$5^2 × (5 × 5)^3 × 5 × 5 × 5 = 5^2 × 5^3 × 5^3 = 5^{11}$
If a =$x^{1/3} + x^{-1/3}$ then $a^3 – 3a$ =
Answer: (c)
$ a=x^{1/3}+x^{-1/3}$
Cubing both sides, we get
$a^3=x+1/x+3(x^{1/3}+x^{-1/3})$
$a^3=x+1/x+3a$
$a^3-3a=x+x^{-1}$
64 × 16 ÷ 256 = $(4)^{(? – 3)}$
Answer: (a)
${64 × 16}/256 = 4^{?-3} = 4 = 4^{?-3}$ = ? - 3 = 1
∴? = 3 +1 = 4
$(6)^4 ÷ (36)^3 × 216 = 6^{(? – 5)}$
Answer: (a)
$(6)^4/(36)^3 × 216 = 6^{(?-5)} = {6^4 × 6^3}/6^6 = 6^{6-5}$
