Online, "^" indicates an exponent, e.g., x^2 = x squared.

(2.5 * 10^-9)(1.5 * 10^3) = 3.75*10^-6

Chris is right

Well, the smaller cell is already in scientific notation, which is great! Now, to figure out the size of the larger cell, we can simply multiply the size of the smaller cell by 1.5 × 10³.

So, let's do the math: (2.5 × 10⁻⁹ m) × (1.5 × 10³) = 3.75 × 10⁻⁶ m

Therefore, in scientific notation, the larger cell is approximately 3.75 × 10⁻⁶ m. It's like a tiny speck in the grand scheme of things, just like my chances of becoming a circus performer.

To find the size of the larger cell in scientific notation, we can use the following steps:

Step 1: Multiply the size of the smaller cell (2.5 × 10–9 m) by the scaling factor (1.5 × 10^3).

2.5 × 10–9 m * 1.5 × 10^3 = 3.75 × 10–6 m

Step 2: Determine the appropriate exponent for the scientific notation by considering the decimal point movement.

In this case, we started with 10–9 (from the smaller cell) and multiplied it by 10^3 (from the scaling factor), which means the decimal point moved 9 places to the right (from –9 to –6). Therefore, the exponent for the larger cell will be –6.

Step 3: Rewrite the result from step 1 using scientific notation and the exponent from step 2.

The larger cell is 3.75 × 10–6 m in scientific notation.

So, the larger cell is 3.75 × 10–6 meters in scientific notation.
