√2 (√45 + √80) can be written in the form a√10 where a is an integer. Find the value of a.
aleksandrvk [35]

Answer:

a = 7

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

\sqrt{2} (\sqrt{45} + \sqrt{80} ) ← distribute parenthesis by \sqrt{2}

= \sqrt{90} + \sqrt{160}

= \sqrt{9(10)} + \sqrt{16(10)}

= \sqrt{9} × \sqrt{10} + (\sqrt{16} × \sqrt{10} )

= 3\sqrt{10} + 4\sqrt{10}

= 7\sqrt{10} → in the form a\sqrt{10}

with a = 7

17 + 0 = 17
additive identity property....which basically states if u add a number to 0, it results in the original number
==============
-16 * -1 = -16
multiplicative identity property...which basically states if u multiply a number by 1, it results in the original number
==============
10 * 1/10 = 1
inverse property of multiplication...which states that any number multiplied by its reciprocal will equal 1. The reciprocal of a number can be found by just flipping the number.
examples :
10 (or 10/1)...its reciprocal is 1/10
4/5...its reciprocal is 5/4
-2 (or -2/1)...its reciprocal is -1/2
