Which expression is the simplified form of ? Which expression is the simplified form of ? @Mathematics
\[\sqrt{k^23\sqrt{?}}\]
i dont think i understand the expression...
Its the square root sign then under it is k^23
u mean this?:\[\sqrt{k^{23}}\]
Yes
you could write the root like this:\[\sqrt{k^{23}} = k^{\frac{23}{2}} = (k^{11} \times k^{\frac{1}{2}}) = k^{11}\sqrt{k}\]
Which expression is the simplified form of \[\sqrt{63w^36}\] ?
the 6 on the end means 36
\[\sqrt{63w^{36}} = \sqrt{63}w^{\frac{36}{2}} = w^{18}\sqrt{63}\]looking at 63^(1/2)\[\sqrt{63} = \sqrt{21 \times 3} = \sqrt{7 \times 3 \times 3} = 3\sqrt{7}\]then you get\[3w^{18}\sqrt{7}\]
Ok i have a couple more can you still help me?
sure
\[\sqrt{5+3 \sqrt {10+2\sqrt{5}}}\]What is the exact value of the expression
\[3\sqrt{10+\sqrt{20}} = \sqrt{90 + 9\sqrt{20})} = \sqrt{90 + \sqrt{1620}}\]hmmm.... i think u need a calculator for this one -.-
well i got like 4.051256372 from the calculator >.>
\[\sqrt{72 - \sqrt{8+\sqrt{128}}}\]What is the exact value of the expression
8.2222402002 i think u can use a calculator for solving these, just watch out for the order of operations
