1b. 15×10¹⁰ kg m²/s²

Explanation:

Remember order of operations (PEMDAS).

1a.

Start by dividing the numbers, the powers of 10 (using exponent rules), and the units.

Take the square root:

Finally, multiply (you'll need a calculator):

1b.

Start by squaring the last term:

Now like before, multiply the numbers, the powers of 10 (using exponent rules), and the units:

find the sum of the two horizontal vectors and the sum of the two vertical vectors
