Answer :
The product of 63.4 x 151, when rounded to the correct number of significant figures (three), is 9570.
The calculation of 63.4 x 151 using significant figures results in a product that must be rounded according to the least number of significant figures in the given numbers. In this case, 63.4 has three significant figures and 151 has three significant figures. Therefore, the product should be reported with three significant figures.
To calculate the product:
63.4 x 151 = 9573.4
When we round this to three significant figures, the result is 9570 because the digit to the right of the hundred's place is a 3, which means we leave the hundred's place as it is.
