Question

1.32 x 10^8 X 2.34 10^4

Answer 1

30888*10^8

Step-by-step explanation:

concept used

law of exponent

`a^x * a ^y =a^(x+y)`

____________________________

1.32 x 10^8 X 2.34 10^4

multiplying 1.32 and 2.34 we have

1.32*2.34 = 3.0888

10^8 X 10^4 = 10^(8+4) = 10^12

thus,

1.32 x 10^8 X 2.34 10^4 = 3.0888*10^12

3.0888 can be written as 30888/10000

1.32 x 10^8 X 2.34 10^4 = 30888/10000*10^12

10000 = 10^4

1.32 x 10^8 X 2.34 10^4 = (30888/10^4)*10^12

concept used now

`a^x / a ^y =a^(x-y)`

1.32 x 10^8 X 2.34 10^4 = 30888*10^(12-4)

1.32 x 10^8 X 2.34 10^4 = 30888*10^8

thus, answer is 30888*10^8
