Question

For adding 5.55x10^4 and 6.95x10^3, first the exponent is made equal.​

Answer 1

Answer:

62.45 x 10^3

Explanation:

(5.55 x 10^4) + (6.95 x 10^3)

55.5 x 10^3 + 6.95 x 10^3

(55.5 + 6.95) x 10^3

62.45 x 10^3

here we convert 10^4 into 10^3 because we cannot add two numbers when their exponent is different.
