Question

Write each of the following in the expanded form :-

(c) $19x^2{y}^2{z}^2$

Answer 1

Explanation:- In the expanded form. we break up a number according to its place value and expand it to show the value of each digit.

So, Expanded form of $19x^2{y}^2{z}^2=19\times x\times x\times y\times y\times z\times z$

as here power of x is $2$, power of y is $2$ and power of z is aslo $2.$

so we write expanded form like shown above.
