Hi can anyone help me with this math question |
|
Answer» a) 5×10³ × 9×10(7) (Here 7 is the power of 10)
= 5 × 9 × 10³ × 10(7) = 45 × 10 (both powers of 10 = 7+3) So it will become. = 45 × 10( 10) here 10 is the power of 10 = 45 × 10(10) B) 7 × 10 (5) ÷ (2 × 10² ) NEXT divide ( 7÷ 2 ) = 3.5 × 10(10) [10 is the power of 10] = 3.5 × 10(10) |
