Question 5
Multiply :
7½ and 8½

Answer 1

The multiplication of given two irrational numbers is $56^{\frac{1}{2}}$

Therefore $7^{\frac{1}{2}}\times 8^{\frac{1}{2}}=56^{\frac{1}{2}}$

Step-by-step explanation:

• Given that $7^{\frac{1}{2}}$ and $8^{\frac{1}{2}}$
• To find the multiplication of two given irrational numbers :
• Now multiply the given irrational numbers we get ,

$7^{\frac{1}{2}}\times 8^{\frac{1}{2}}$

$=(7\times 8)^{\frac{1}{2}}$ ( using the property $(a\times b)^m=a^m\times b^m$ )

$=56^{\frac{1}{2}}$

Therefore we have $7^{\frac{1}{2}}\times 8^{\frac{1}{2}}=56^{\frac{1}{2}}$
