What is the units digit of (13)^4(17)^2(29)^3 ?

Rewrite the product as

Powers of 10 and multiples of 10 don't contribute to the units digits, so we only need to consider the product

and we can treat this the same way:

Again, ignore the multiples of 10 to reduce this to the product 1*9*9 = 81, whose units digit is 1.

4.5%

step-by-step explanation:

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
