Question

Work out(leave in standard form)
7x10^3-2.4x10^2

Answer 1

-797/691=^6/18//65-89

Answer 2

To work out the expression in standard form, subtract the exponents and perform the necessary calculations. The result is 4.6x10^1 or 46.

Step-by-step explanation:

To work out the expression in standard form, we can subtract the exponents and perform the necessary calculations. The given expression is 7x10^3 - 2.4x10^2.

1. Subtract the exponents: 3 - 2 = 1.
2. Multiply the coefficients: 7 - 2.4 = 4.6.
3. Write the result in standard form: 4.6x10^1 or 46.
