(b) 5.67 × 10^-5

II.

5. 25×5^x =5^8

5^2×5^x =5^8

5^2+x =5^8

Answer 2

Answer:

question 4

a). 5.74 x 10 raised to power 6.

b). 5.67 x 10 raised to power -5.

question 5

• 25×5 Ki power x x = 5 ki power 8

⟹5 Ki power 2 × 5 ki power x = 5 ki power 8

[∵ 25 = 5 × 5 = 5 ki power 2]

⟹5 ki power 2+x = 5 ki power 8

[∵a ki power m ×a ki power n =a ki power m+n]

⟹2+x=8 [∵a ki power m = a ki power n ⟹ m = n]

∴ x=6
