Work out the value<br> of <br> 2. 4510 ×10to the power of 9<br> 1.15 × 10 to the power of 3
Simora [160]

Answer:

The result in standard form is: 2.3 \times 10^{6}

Step-by-step explanation:

Dividing the values:

To find the real part, we divide 2.645 by 1.15. So

2.645/1.15 = 2.3

Finding the power:

Its a division, so we keep the base, and subtract the exponents. So

\frac{10^9}{10^3} = 10^{9-3} = 10^{6}

Result in standard form:

The result in standard form is: 2.3 \times 10^{6}

Yousef borrowed last term for tuition, books, and student fees. This term he plans to borrow because he knows his classes will b
Len [333]

The estimate of the amount of money Yousef will borrow by first rounding to the hundred is 4000

<h3>Estimate the amount of money Yousef will borrow by first rounding to the hundred</h3>

The amount borrowed are given as:

Last term = 1690

This term = 2345

When the amounts are rounded to the nearest hundred, the amounts borrowed become:

Last term = 1700

This term = 2300

The total amount is then calculated as:

Total amount = Last term + This term

Substitute the known values in the above equation

Total amount = 1700 + 2300

Evaluate the sum

Total amount = 4000

Hence, the estimate of the amount of money Yousef will borrow by first rounding to the hundred is 4000
