If you're looking for the Euclid Algorithm, try going with these ↓
137 - ( 27 × 5) = 2
27 - ( 2 × 13) = 1
2 - (1 × 2) = 0
GCF → 1
70,000,000+8,000,000+600,000+20,000+1,000+80+7 = 78,621,087
When you multiply radical expressions you multiply the numbers under the radical symbols.<span><span>3–√</span>×<span>7–√</span>=<span>21<span>−−</span>√</span></span>
When you add radical expression you CANNOT add the numbers under the radical symbols.
<span><span>3–√</span>+<span>7–√</span>≠<span>10<span>−−</span><span>√</span></span></span>
