Express the product of 4.0 x 10^-2 m and 8.1 x 10^2 m using the correct number of significant digits

The product of two expressions is 32.40

Step-by-step explanation:

Two numbers given are and

and we have to express the multiplications of these two numbers.

In this question we will multiply the numbers and add the powers of 10s.

So multiplication gives us

So we can express the product as 32.40

32 (two significant figures)

Step-by-step explanation:

We are given these two numbers written in scientific notations and we are to find their product, using the correct number of significant digits:

4.0 x 10^-2m and 8.1 x 10^2 m

Here, the exponents will cancel each other as one is negative and the other one is positive so we will be left with:

4.0 x 8.1 = 32.4

To two significant figures, it will be 32.

entering that problem on the tube might get you an answer

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
