- 5. (6)^6.5 × (36)^4.5 ÷ (216)^4.5 = (6)^?
A. 1
B. 2
C. 4
D. 6
Here is the answer and explanation
Answer : Option B
Explanation :
(6)^6.5 × (36)^4.5 ÷ (216)^4.5
= (6)^6.5 × [(6)^2]4.5 ÷ [(6)^3]4.5
= (6)^6.5 × (6)^9 ÷ (6)^13.5
= (6)^(6.5 + 9 - 13.5)
= (6)^2 - 9 years agoHelpfull: Yes(41) No(0)
- approximately ==1.08.
ans is 1(a) - 9 years agoHelpfull: Yes(6) No(23)
- you guys get it wrong i guess...I think the question is (6^6.5) * (36^4.5) / (216^4.5) = (6^?)
Soln:
[sqroot (6^13) * sqroot (36^9)] / sqroot (216^9)
= (6^6)sqroot(6) * (36^4)sqroot(36) / (216^4)sqroot(216)
= 36 i.e (6^2)
so Ans is 2. - 9 years agoHelpfull: Yes(4) No(1)
- a) 6.5/6= 1.08 so approximately 1
- 9 years agoHelpfull: Yes(2) No(1)
- (6)6.5*(36)4.5/(216)4.5
=(6)6.5/(6)
=6.5 => (6)1.08 = 6.5 approx - 9 years agoHelpfull: Yes(2) No(2)
- 6)6.5 × (36)4.5 ÷ (216)4.5
= (6)6.5 × [(6)2]4.5 ÷ [(6)3]4.5
= (6)6.5 × (6)9 ÷ (6)13.5
= (6)(6.5 + 9 - 13.5)
= (6)2
so B is the correct ans - 8 years agoHelpfull: Yes(2) No(0)
- using Bodmas the ans which I got is 1312=1.08 (approx) so 1 is the ans option A

- How ?? can any one write solution.. ?

- This question is like this----- (6)^6.5*(36)^4.5/(216)^4.5=6^x---
And the ans will be 2 after solving...... so option no B is right. - 9 years agoHelpfull: Yes(0) No(0)
- i would say,,,1.08 near equal to 2...so i would choose B) as the right answer.:D
- 9 years agoHelpfull: Yes(0) No(18)
- (6)6.5 × (36)4.5 ÷ (216)4.5
= (6)6.5 × [(6)2]4.5 ÷ [(6)3]4.5
= (6)6.5 × (6)9 ÷ (6)13.5
= (6)(6.5 + 9 - 13.5)
= (6)2 - 8 years agoHelpfull: Yes(0) No(0)
