Question

1) work out the value of (1.7x10^4)x (8.5x10^-2) give your answer in standard form.
2) work out the value of (6.8x10^2)x (1.3x10^-3) give your answer in standard form

Answer 1

Step-by-step explanation:

Standard form is a way of writing a small number or a large number easily.

We should give the final answer in standard form.

1) (1.7 × 10⁴) × (8.5 × 10⁻²)

We enter this directly into the calculator to obtain a solution.

= 1445

We write this in standard form we have :

1.445 × 10³

2)  (6.8 × 10² ) × (1.3 × 10⁻³) = 0.884

In standard form :

8.84 × 10⁻¹
