Question

.




plz solve it plz step by step plz​

Answer 1

(a) - (don't know, sorry)

(b) Move the decimal 3 times to the left in the number so that the resulting number, m = 3.4, is greater than or equal to 1 but less than 10

Since we moved the decimal to the left the exponent n is positive

n = 3

Write in the scientific notation form, m × 10^n

= 3.4 × 10^3
