If 43m = 0.086, then the value of m is
(a) 0.002
(b) 0.02
(c) 0.2
(d) 2

Solution:

Let’s find the value of m in the equation 43m = 0.086

43m = 0.086

m = 0.086/43

m = 0.002

Hence out of the four options, the correct option is (a) 0.002

✦ Try This: 10. If 32m = 0.096, then the value of m is (a) 0.002, (b) 0.02, (c) 0.003, (d) 0.03

Here, 32m = 0.096

m = 0.096/32

m = 0.003

Hence out of the four options, the correct option is (c) 0.003
